ZTELEC three-phase dry-type transformers have a capacity of 0.03KVA ~ 2500KVA.
This series of three-phase dry-type transformers is a fairly mature product made by ZTELEC after years of screening various high-quality materials and advanced process technologies. It has the advantages of moisture-proof, easy maintenance, and extremely high efficiency. It can penetrate the load center and can be used. Power transmission and distribution sites such as subways, stations, terminals, enterprises and tunnels. The product is applicable to various power supply places where the AC 50 ~ 60HZ and the voltage does not exceed 24KV. The various input and output voltages of the products, the connection groups, and the distribution of the tap line group capacity can be carefully designed and manufactured according to the user’s requirements.
When the grid voltage is 20kv or 10kv, the transformer in this series can control the connection status between two windings on high voltage coil in each phase via conversion device, and realize voltage conversion through series or parallel connection without changing the output voltage, thus enabling one transformer to connect with two electrical voltage systems like 10kv or 20kv asynchronously, where the transformer acts as a transition of upgrading the grid voltage from 10kv to 20kv. In this way, it can achieve repeated investment reduction, efficient conversion, and stable performance.
